That was 2 years ago, on a flat wicket, in a Twenty20 game. If you're basing his whole career and his talents on that 1 over, then it shows how warped your opinions are. He's a miles better bowler now than he was then.
Sky Speedguns may have been exaggerated at Lords, but even after Lords, Broad was timed at consistently quicker than Fidel Edwards, Jerome Taylor and James Anderson. You don't beat an experienced batsman like Sarwan, who's in excellent form for pace on two occassions bowling at 86mph. Broad is genuinely quick nowadays.
It may be the Windies, but he's actually bowled well, and if you'd watched it you'd know that. He's not picked up cheap wickets of the tail, he gets good batsmen out with good deliveries, especially in ODi cricket. He'll prove you wrong, which tbh wouldn't be a huge surprise having read quite a few of your posts on CW, you were hardly the most respected and knowledgable member on there, so it wouldn't be a massive surprise to see you proven wrong once again, this time on here.
